PurityPlus® Grade 6.0 Gases by Arc3 Gases: Increased Production, Greater Cost Economies Those who use critical gases are adamant about having high-quality Carrier Gases for chromatography and the entire range of analytical applications. Supplying these gases ought to be a primary capability of any specialty gas producer. Over the past forty years, the limited detection abilities of conventional technology as well as ever-evolving analytical methods have rightly put more demand on these gases. The gas specifications that took care of 1970s needs well enough may prove inadequate as this century progresses. Meeting or transcending ever new specs necessitates a continual investment by the gas supplier – in instrumentation and purification equipment, in tutelage to get optimal performance from these tools, and in frequent review, testing, and verification of manufacturing and quality processes. In order to stay a step ahead of your needs, we’re upgrading our ability to create and certify the gases you depend on in the 21st century. So what are you purchasing? And what are you measuring? And what’s to be gained by acquiring the highest-purity gas you can afford? Let’s look closely at the PurityPlus Specifications. PurityPlus Helium, UHP, 5.0 Ultra Carrier, 5.5 Chromatographic, 6.0 Minimum Purity 99.999% 99.9995% 99.9999% Oxygen < 2 ppm < 1 ppm < 0.5 ppm Moisture < 2 ppm < 1 ppm < 1 ppm Hydrocarbons <0.5 ppm < 0.5 ppm < 0.2 ppm Nitrogen < 4 ppm < 1 ppm Carbon Monoxide < 0.1 ppm Carbon Dioxide <0.1 ppmWhat’s it all mean? If you’re measuring processes with components in percentage ranges, 5.0 gases are usually okay. If you’re measuring impurities in the 10–1,000 ppm range, you’ll realize a flatter baseline and more precise measurements using 5.5 gases. And if you’re performing contaminant detection and quantification below 10 ppm, you’ll come out ahead using 6.0. In any event, recognizing standards isn’t all there is to it. There’s also our process]86]. Are your cylinders pre-treated to avoid eventual contamination from sidewall corrosion and degassing? Ours are. Are the instruments used to confirm these specifications continually calibrated using traceable standards? Ours are. And can this calibration be documented? Ours can.
